HINGE.

SPECIFICATION forming part of Letters Patent No. 377,310, dated January31, 1888.

Application filed October 3, 1887. Serial No. J5L327. (Model) T aZZ whomit may concern:

Be it known that I, FRANK H. KNIGHT, a citizen of the United States,residing at XVashington, in the District of Columbia, have inventedcertain new and useful Improvements in Hinges; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to improvements in hinges; and it consists,essentially, in the con struction and arrangement of the several partscomprised therein for service substantially as hereinafter described,and illustrated in the accompanying drawings, wherein similar fig uresof reference denote similar parts.

In said drawings, Figure 1 is an elevation of my improved hinge, showingthe same applied to a shutter or door and in open or locked position.Fig. 2 is a sectional view taken on the line of Fig. 1, looking downwardtoward the hinge. Figs. 3, 4, and 5 are views showing the hinge in thedifferent positions it assumes while the shutter or door is being openedor closed. Figs. 6 and 7 represent a side elevation and a top plan view,respectively, of one of the leaves (that fixed to the hanging-stile) ofthe upper hinge. Figs. 8 and 9 are similar views of the remaining leafof the upper hinge. Figs. 10 and 11 represent, respectively, a sideelevation and a top plan view of the fixed leaf of the lower hinge.Figs. 12 and 13 are similar views of the swinging leaf of said lowerhinge. Fig. L is a sectional view taken on the line y y of Fig. 13. Fig.15 is a similar sectional view taken on the line 2 z of said Fig. 13,and Fig. 16 is a sectional view taken on the line in m of Fig. 3.

In the present embodiment of my invention I have shown an ordinarywindow blind or shutter, 1, inovably connected to a hanging stile, 2, byreversible hinges 3 and 4, which, although differing from each other, toa considerable extent are yet arranged to coact with each other to forma perfect swinging support for a blind or shutter, and which areconstructed, respectively, in the manner which I will now proceed todescribe. Of said hinges the upper, 3, consists of two leaves, 5 and 6,which, as are also the leaves of the lower hinge, are provided withsuitable apertures to receive screws or nails, by which they are securedto a hangingstile and blind, door, 860., respectively. The former, 5, ofsaid leaves is provided with a forwardly-projecting portion, 7, whichterminates in an enlargement, 8, that carries an upwardly-projectingpintle, 9, and is also provided at the opposite sides of said pintle andupon its upper surface with slight inclines 10, which engage one or theother of similar inclines, 11 and 12, that are formed upon the oppositesides of an enlarged head, 13, which in turn is formed upon a projectingportion, 14, of the leaf 6 and at each side of an aperture, 15, thatextends through said head 13 for the reception of the pintle 9.

By reference to Figs. 1, 6, 7, 8, and 9 it will be seen that the uppersurface of the projee tion 7 of the leaf 5 extends in different planes,and that said surface is adapted to closely engage one or the other ofthe surfaces of the projection 14 of the leaf 6 when the hinges are inopen position. It will also be observed, and more especially byreference to Figs. 7 and 8, that while the pintle 9 is placed in theplane of the body portion of the leaf 5, the aperture 15 in the leaf 6for the reception of said pintle is not in the plane of the body of saidleaf, but is rather at one side thereof, the object of such constructionbeing to permit the complete hinge to act either as a right or a lefthand'hinge, as will be readily understood. The upper hinge thusconstructed is adapted to co-operate with a lower hinge, 4, whichconsists in two leaves, 16 and 17, the former of which is also providedwith a forwardly-projecting portion,18, terminating in an enlarged head,19, carrying an upwardly-projecting pintle, 20, which is placed in theplane of the body of the leaf l6,and is provided upon the side adjacentto the body of the leaf with locking-studs 21 and 22, which are arrangedat a short distance from each other and operate toprevent accidentaldisplacement, both lateral and vertical, of the blind.

By reference to Figs. 1, 10, and 11 it will be.

observed that the upper surface of the projecting portion 18 of the leaf16 extends in different planes, and that said projection is provided atits outer end with an upwardlyprojecting guide-stud, 23, and also atopposite :0 sides of the pintle 20 with inclines 24, the forward edgesof which are in alignment with the rear surface of the pintle 20. Theremaining I part of the hinge 4viz., the leaf 17-is also provided with aforwardly-proj ecting portion,

25, which is provided near its outer end with "an'elongated' aperture orslot, 26, which extends in a plane parallel with the plane of the bodyof the leaf, to receive the pintle 20, and upon opposite sides of saidslot 26, upon each 20 side of the projection 25, with flanges 27 and 28,the inner surfaces of the latter of which are coincident with one sideof said slot 26,

while the inner surfaces of the remaining flanges 27 are curved outwardfrom said slot to provide recesses 29, in which the lockingstuds 21 and22 move when the complete hinge is being opened and closed. (See Figs. 3

and 4.)

The flanges 27 are extended in curvedplanes 3o rearwardly toward thebody of the leaf, to form, in connection with the rear'ends of theflanges 28, recesses 30, into one or the other of which the guide-stud23 is swung (accordingwas the hinge is a right or a left hinge) when thehinge is opened, (see Figs. 1, 2, and 3,) to facilitate which result Icurve the outer surfaces of the flanges 28 at the points 31, as shown.The outer ends of the flanges 27 and 28 are beveled or inclined at a, tooperate in unison with the inclines 24, as will be hereinafterdescribed.

The operation of my improved hinge is as follows, assuming the blind orshutter to be closed and the several parts of the hinge 4 to be in theposition shown in Fig. 5, the pintle 20 resting against one end of theslot 26, while the guide-stud 23 bears against the outer end of theprojection 25: When the blind is swung outward, the lockingstuds 21 and22 upon the pintle 20 will swing into the recesses 29, (see Fig. 4,) andwill, by impinging against the sides of said recesses, (the flange 27,)move the pintle 20 toward the opposite end of the slot. The continuedoutward movement of the I blind will next bring the guide-stud 23 intoone or the other of the recesses 30, whereby said stud, by impingingagainst the curved side of said recesses, (see Fig. 3,) will move theleaf 17 outward until the inclines a of said leaf coincide with theinclines 24 of the leaf 16 and the said inclines are, by the weight ofthe blind or shutter, moved into engagement, by which the locking-studs21 and 22 will be moved into the recesses 32 and 33 between the ends ofthe flanges 27 and 28, and the guidestud 23 will be moved against theforward side of the recess 30, thus locking the blind in open position.(See Figs. 1 and 2.)

It will be observed that the stud 22 serves a twofold functionviz., toaid the stud 21 in maintaining the blind in open and locked position,and also to prevent the vertical displacement of said blind when open.

It will be. observed that the inclines 10 and 11, or 10 and 12, as thecase may be, of the hinge 3 come into engagement simultaneously with theengagement of the inclines 24 and a of the hinge 4, and willconsequently aid said latter inclines when the blind or shutter is to beclosed.

To close the blind or sh utter,a slight inward pressure only isnecessary to move the parts of the hinge 4 into the position shown inFig.

3, in which position the parts 16 and 17 of the hinge 4 are unlockedfrom each other, after which the blind may be readily drawn inward,

the parts 16 and. 17 moving upon each other in similar manner butopposite direction to that hereinbefore described. I

While I have herein shown the pintle 20 as having two locking-studs, 21and 22, I yet do not confine myself to such construction, inasmuch asone of said studs may be dispensed with without detracting from theoperation of my invention. Again,it is not essential to the properworking or locking of the blind, shutter, &c., that the hinges 3 and 4thereon be of different construction, as herein shown, since each ofsaid hinges may be similar in construction to the hinge 4 andsuccessfully accomplish the desired result. Again, the swinging portion17of the hinge4 may be provided upon one side only with flanges 27 and28, in which case the hinges 4 will be formed into regular right andleft hand hinges.

\ Various other modifications in detail of con- 1 struction may be madein my invention without departing from the spirit or sacrificing theadvantages thereof. I therefore claim the right to make suchmodifications therein as shall properly fall within the scope and limitof said invention.

Having thus described my invention, I

claim-- 1. A hinge comprising a leaf having a pintle, a locking-studupon said pintle, and a guiding-stud separate from said pintle, and aleaf having a slot to receive said pintle and separate recesses toreceive said locking-stud and said guiding-stud, respectively,substantially as described.
